THE CRUCIAL IMPORTANCE OF ENERGY

The crucial importance of energy

The production of energy from fossil fuels produces carbon dioxide (CO2), which is one of the main causes of the greenhouse effect and therefore of global warming.

Renewable energies: energies of the future

The tips that follow help reduce energy consumption by changing (a little) our habits, our equipment or by using alternative techniques, sometimes sources of savings. The building sector represents, for France, the second source of greenhouse gas emissions, the first being transport.

Renewable energiesRenewable energy sources are available in unlimited quantities. Their exploitation is a way to meet energy needs while preserving the environment. The main forms of renewable energy are:

solar energy,

wind power,

energy from biomass,

geothermal energy,

Hydro-electric power.

In 2015, if the countries of the European Union succeed in meeting their commitments, the electricity produced in Europe should come from 25% of renewable energy sources.
